For those of you out there that just installed Fedora 10 and get your Epson DX7450 (or maybe other types) working perfectly
but CANT USE the Scanner Tool I may be able to help

If you are getting the message "No devices available" when you run the Scanner Tool - xsane
do this:

log in as root and open a terminal window

run the command:
Code:
sane-find-scanner
(with the multifunction printer ON of course)

it will tell you that found a USB scanner with vendor=xxxxxx, product=yyyyyy

copy those numbers and now edit this file:
Code:
/etc/sane.d/epson.conf
uncoment the last two lines:
Code:
usb /dev/usbscanner0
usb /dev/usb/scanner0
now add the folowing line to the USB section of the file (the last section)
Code:
usb xxxxxx yyyyyy
now it should work

hope this helped
Linux IS the future!
